A-D Normality test

When I use minitab to test for normality with a norm plot and use the
Anderson-Darling choice it reports two numbers (actually more, but
only two that have me confused); p and A^2. I observe that p goes up
with better fits and A^2 seems to go down. I'm guessing that p
represents something like the probablility of a getting a fit this bad
or worse from a normal population, and I have no clue about A^2. Can
someone give a good definition of the meaning of these two values, and
..... How are they derived?

Thanks
